Introduction

This is the complete onboarding task flow for in-place archive mailboxes from On-Premises Exchange servers (versions 2007 and later) to in-place archive mailboxes on Office 365. Complete each step in the order listed. Links to corresponding Knowledge Base articles are provided.

If a mailbox migration project has already been performed, the same administrative credentials that you used during your mailbox migration project can be used for this project. It is likely that you have already performed all of the steps in each section, other than the MigrationWiz Steps. Proceed to the MigrationWiz section of this guide.

MigrationWiz is a migration solution (not a synchronization solution) and will NOT propagate updates, deletes, or moves of the items previously migrated in the first migration pass because we do not have “live” monitoring of changes (as with a sync agent) and we cannot handle scenarios such as conflict resolution without user interaction.

MigrationWiz supports the capability to share migration projects across a Workgroup. When the Project Sharing feature is turned on, all Agents besides those who are Inactive can view all migrations projects. For more information, visit Project Sharing in MigrationWiz.

Prepare the Source Exchange Environment

Note: If you have already completed a mailbox migration project against this Source environment, these steps will already have been completed.

MSPComplete Steps

Note: If you have already completed a mailbox migration project against this Source environment, these steps will already have been completed. The endpoints that were created for your mailbox migration project can be used for your in-place archive migration project.

MigrationWiz Steps

Create an In-Place Archive Migration project.Important: Remember that this is an in-place archive migration project. It is not a mailbox migration project. Read the How do I create a new migration project? article for more information.

The following options are the most valuable for this migration scenario:

Set your preferred Destination.Note: The default is to migrate into mailboxes, rather than archives, at the Destination. To change this, set Destination: Microsoft Office 365 > migrate to: Archive. What are my mailbox or archive migration options?

Set Maximum concurrent migrations. If the Source server has enough server resources, set this parameter based on the bandwidth guideline of three (3) mailboxes per 1Mbps of bandwidth. Therefore, for example, if there is a 10Mbps connection, we recommend setting the maximum concurrent migrations parameter to be 30. If the Source server has very few available server resources (e.g., it is running low on memory or it has a very high CPU utilization), we recommend setting this value to a lower number to avoid overwhelming the Source server with requests.
